PRINTERS GUIDE SETTEB AND REGISTERING Specification of Letters Patent.

Application filed June 23, 1919. Serial No. 306,192.

To all whom it may concern:

Be it known that I, MEYER Louis ARON- SON, a citizen of the United States of America, residing at Hartford, in the count of Hartford and State of Connecticut, ave invented certain new and useful Improvements in Printers Guide Setter and Registering Aid, of which the following is a specification.

The primary object of the invention is the provision of a simple and inexpensive device for printers use whereby printing in a plurality of colors is greatly facilitated for the accurate registry of the successive impressions, the invention being also serviceable by the press-man in setting the pins or quads upon the tympan sheet.

A further object of the invention is the provision of means for printers use whereby type or printing plates or both are readily arranged for locking in the chase to pr0- duce accurate printing with different parts in different colors, the invention being capable of repeated use, being instantly adjusted when required and taking up little room when not being used.

With these general objects in view the in- .vention consists of the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawing and then claimed.

In the drawing forming a part of this application like reference characters designate corresponding parts throughout the several viewsand in which,

Figure 1 is an elevational view of a portion of my invention illustrating its use for setting guides upon the bed of a printing press, and

Figure 2 is a similar view showing the employment of my invention as an aid for adjusting type for accurate registry in color prlnting.

Referring more in detail to the drawing, my invention consists of a sheet 10 of transparent material such as isinglass or celluloid, rectangular in form and of suitable dimensions, equally divided into a plurality of squares 11 after the manner of section-paper employed by engineers. The squares 11 are formed by straight lines or rulings 12 and 13 in perpendicular arrangement and in accordance with the American standard rule, dividing the entire sheet 10 into one-eighth inch or one-sixteenthinch squares 11.

Scale readings 14 and 15 extend in opposite directions preferably adjacent each edge 13 and 17 of the sheet 10, these readlngs being figures equally spaced apart, such as a distance of eight of the squares 11 as illustrated in the views of the drawing.

.The platen 18 of a bed-and-platen printing press has the usual tympan sheet 19 stretched across the same secured by clamps 20 only one of. which is illustrated in Fig. 1 of the drawing and the printed matter appearing in one color such as black is impressed upon the tympan sheet 19 being illustrated by dotted lines 21. By placing the transparent sheet 10 over the impression 21 and emplo ing the rulings 12 and 13 the press-man Wlll accurately ascertain where the pins or quads 22 are to be placed for positioning the words 21 as desired upon the finished work during the printing operation. The showing of the words 21 through the sheet 10 and the equal dimensions of the squares 11 permits the guides 22 to be quickly and accurately placed upon the tympan sheet 19.

A further use of my invention being to help the printer to lock up the form where more than one color is being employed so that the next impression of a differently colored ink will be made at exactly the proper place upon the paper, I have illus trated in Fig. 2, a chase 23 with three type letters 24 to be printed in the next impression to read with the letters 21 of the first impression, The invention will assist in the work of color printing when type and plates or both are employed. In using black and red ink for instance, the stone man is given the transparent sheet 10 and prints the letters 21 thereon by placing the sheet 10 against the guides 22 in the position for printing, such impression being shown at 25 upon the sheet 10 in Fig. 2 of the drawmg.

The stone man now takes the new letters 24 for the red ink work for looking into a form and by placing the isinglass guide 10 with the black ink impression 25 thereon directly over the new letters 24 and the latterv are shifted to correct positions and the form is locked in the chase 23 for fitting in the printing press. The guides 22 remain in their original positions as set for printing the letters 21 in black and the red ink portion of the job is run off, accurately printing the red letters 241 with respect to the black letters 21. In this manner, type and plates may be printed in different colors readily adjusted to accurately register in any manner desired for printing superposed or side by side, my invention serving to render the printing in colors as well as at desired points upon the sheet a mathematically accurate calculation rather than mere guess work as ordinarily practiced heretofore. The use of the American standard rule for the lining of the isinglass sheet 10 renders the invention capable of universal use while it will be apparent that the shape and dimensions may be changed at will as well as minor other variations if desired MEYER LOUIS ARONSONJQ
